VALVE.

SPECIFICATION forming part of Letters Patent No. 782,003, dated February'7, 1905. Application filed June 7, 1904. Serial No. 211,471.

To a]! whom, it may concern.-

I Be it known that I, CHARLES PATRICK CAR- LIN, a citizen of the UnitedStates, and a resident of hicago, in the county of Cook and State ofIllinois, have invented a new and Improved Valve. of which the followingis a full, clear. and exact description.

This invention relates to improvements in pressure-actuated valves, theobject being to provide a valve of this character having very few andsimple parts not liable to get out of order and that may be made at acomparatively small cost.

I will describe a valve emboding my invention and then point'out thenovel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a longitudinal section showing a valve mechanism embodyingmy invention. Fig. 2 is a section on the line 20 w of Fig. 1, showingthe valve open. Fig. 3 is a section on the line .12 ;I' of Fig. 2. Fig.4 is a section on the line 1/ of Fig. 2.

Referring to the drawings, 1 designates a casing or sleeve, to one endof which a pipe 2 connects, and connected to the other end is a nipple3, having its inner open end contracted and forming a valve-seat A. Atthe outer end the nipple is connected, by means of a coupling-collar 5,with a pipe-section 6. The valve '7, operating in the casing 1, issubstantially cup-shaped and has its closed end convcxed, as indicatedat 8, to engage with the valve-seat1, the opposite end being open. Inits side wall the valve is provided with V ports 9, which are oftriangular form, and the ends adjacent to the valve-seat open through anannular shoulder 10, which is somewhat larger than the contracted end ofthe nipple.

In case the valve is used in a horizontal pipe the valve is heldvieldingly against its seat by means of a spring 11, which engages withthe inner end of the pipe 2 and with the end of the cu pshaped valve 7.It may be here stated that in case the valve is used with an uprightpipe the spring may be omitted and the valve closed by gravity.

Having thus described my invention, I claim as new and desire to secureby Letters Patentl. A valve mechanism comprising a casing,a nippleextended therein and having a contracted open end, a cup-shaped valvemovable in the casing and havingaconvexed end portion for engaging insaid opening of the nipple, an annular shoulder formed around saidconvexed portion, and ports formed through said shoulder and through theside wall of the valve.

2. A valve mechanism comprising a casing,a nipple extended therein andhaving a contracted upper end. a cup-shaped valve movable in the casingand having a convcxed end portion for engaging in said end of thenipple, an annular shoulder formed around said convexcd portion, portsformed through said shoulder and through the side wall of the valve, anda spring for moving the valve to closing position.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

CHARLES PATRICK CARLIN.
